Liaison activity

We reviewed the discussion of last week: The group reviewed what happened at IIW and discussed how UMA could fit into the AXN; David Coxe had presented about this at IIW. Sal also reported on his liaisons with external groups. The PDS case study and opportunities to promote UMA in connection with it were also discussed.

Eve is already planning to ensure that we coordinate with Dave and Pam on UMA/AXN integration. This is going to need enhancement of our resource set registration protocol and some standardized attribute schemas. She'll propose a meeting in the first week of December.

Keith reports on his efforts to liaise with the new Attribute Management discussion group. It seems to have a strong connection to ID/Dataweb already, and ID/Dataweb already has a strong connection to UMA.

AMWG liaison

Podcast idea

It was suggested that we publish 10-minute podcasts that would make it easier for people new to UMA to understand what's going on. One idea is to start with an edited version of the webinar recording! Eve will try to play with that.

Healthcare case study

People need more time to read this material. Let's discuss in the Nov 29 all-hands meeting.

Dynamic client registration draft review

Justin Richer is now the primary editor of this spec: hurrah. Let's plan to review it in the Nov 29 all-hands call.

Discussion of recent technical issues

Yuriy of Gluu has been implementing UMA and brought up some questions.

Confusion around the use of UMA-style scopes for the OAuth-specific PAT and AAT scopes: Let's explain this better in the spec so that the confusion can be avoided. We are providing machine-readable metadata at the end of the URL, to illustrate how UMA would make scopes be more machine-readable, but this is not used by the OAuth security mechanism.
The lack of a single consistent outermost JSON property in the AM's response to a request for RPT status: It's proposed to add an outermost "rpt_status" property, whose value is empty if the RPT is invalid. We'll consider this, but it's still open.

Implementation and testing news

The Gluu/OX team is publishing its UMA code under the "MIT open source license". They have a few client-side UMA tests in the oxAuth-client library.

Mike has reported: "A GUI for the UMA tests would be really nice to have. OpenID Connect has one and so does the OX Graph project. I can volunteer to publish the tests, but we'd need to schedule some time to build the UI. Perhaps by year end we could do it." Keith expresses interest in following the test development work closely. We should try and ensure that the Gluu tests don't discriminate against UMA's "Alice-to-*" sharing use cases.
